(Statistics: compute mean and standard deviation) In business applications, you are often asked to compute the mean and standard deviation of data. The mean is simply the average of the numbers. The standard deviation is a statistic that tells you how tightly all the various data are clustered around the mean in a set of data. For example, what is the average age of the students in a class? How close are the ages? If all the students are the same age, the deviation is 0.

Here is a sample run:
Enter 10 numbers: 1 2 3 4.5 5.6 6 7 8 9 10 
The mean is 5 .61
The standard deviation is 2.99794

So, as a good parent Ron want his son to learn about the important stuffs So he started to train his son. His baby has just learned to count two-digit average at school, but is unable to get an average of more than two numbers. The chef, being very busy, needs help from you to write a plan so that the child chef can simply enter the numbers and get the maximum number of numbers at once. Your task is to write a system that accepts a list of N numbers from the same members A and then prints list B where B [i] shows the ratio of the first numbers to fixed A in Python Programming Language. Input: 1 3 246 Output: 234arrow_forward[PYTHON LANGUAGE] You are planning an outing with some friends and need to calculate the total price of the tickets. A regular ticket usually costs $3.99 and a stu- dent ticket costs only $2.99. If the total number of tickets being ordered (including both students and regular tickets) is at least 10, then a 10% discount is applied to the order. However, if it is a holiday, then the at-least-ten group discount is only 5% (not 10%). Write a program that takes three lines of input: the number of reg- ular tickets, the number of student tickets, and an integer indicating whether it is a holiday (1) or not (0). It prints a float giving the total cost. Be sure to define and use constants for REGULAR TICKET PRICE and STUDENT TICKET PRICE. Write your program in a file named tickets.py.arrow_forward(Data processing) Your professor has asked you to write a C++ program that determines grades at the end of the semester. For each student, identified by an integer number between 1 and 60, four exam grades must be kept, and two final grade averages must be computed. The first grade average is simply the average of all four grades. The second grade average is computed by weighting the four grades as follows: The first grade gets a weight of 0.2, the second grade gets a weight of 0.3, the third grade gets a weight of 0.3, and the fourth grade gets a weight of 0.2. That is, the final grade is computed as follows: 0.2grade1+0.3grade2+0.3grade3+0.2grade4 Using this information, construct a 60-by-7 two-dimensional array, in which the first column is used for the student number, the next four columns for the grades, and the last two columns for the computed final grades. The program’s output should be a display of the data in the completed array. For testing purposes, the professor has provided the following data:arrow_forwardExercise B: Some initial values may make the PageRank algorithm converge faster, you can use a program to try different initial values. You can use a smaller floating number precision (fewer decimal places) to converge faster. Or you can assume if the PageRank values change in less than a certain percentage (e.g., 5%), they are converged.arrow_forward"NEED ONLY CODE NO EXPLANATION" Harry has a big wall clock, that got hit while he was playing. Now, the minute hand doesn't rotate by the angle 2π/3600 each second, but now it moves according to different angle x. You can assume that coordinates of the centre of the clock are (0, 0) and the length of the minute hand is l. One endpoint of the minute hand is always located at the clock centre; the other endpoint is initially located at the point (0, l). One second later, Harry observes that this endpoint is at distance d above the x-axis, i.e., the y-coordinate of this endpoint is equal to d. Harry is curious about where the minute hand will be (specifically, its y-coordinate) after t seconds. Because t can be very large, Harry can't wait for that moment. Please help him to write a python code that prints a single line containing the output.

Since the introduction of the Gregorian calendar (in 1582), the following rule is used to determine the kind of year: if the year number isn't divisible by four, it's a common year, otherwise, if the year number isn't divisible by 100, it's a leap year. otherwise, if the year number isn't divisible by 400, it's a common year. otherwise, it's a leap year. none of the above year int(input("enter the year")) if (year%4 1-0) and (year%400 -0) or (year % 1000): print (year is common year") else: print(year, is leap year") year= int(input ("enter the year")) if (years !-0) or (year480 1-0) and (year % 1001-0): print(year is common year") else: print(year, "is leap year") D year= int(input("enter the year"))arrow_forwardYou have to make sure that all the variables you use in your solution are floats.
